reids简易开发--C语言

1.安装hiredis

redis-4.0.9/deps/hiredis目录下

make

make install

可以看到库的流向：

mkdir -p /usr/local/include/hiredis /usr/local/lib

cp -a hiredis.h async.h read.h sds.h adapters /usr/local/include/hiredis

cp -a libhiredis.so /usr/local/lib/libhiredis.so.0.13

cd /usr/local/lib && ln -sf libhiredis.so.0.13 libhiredis.so

cp -a libhiredis.a /usr/local/lib

mkdir -p /usr/local/lib/pkgconfig

cp -a hiredis.pc /usr/local/lib/pkgconfig

2.运行

设置动态库路径：

export LD_LIBRARY_PATH=/usr/local/lib:$LD_LIBRARY_PATH

一般正式环境设置在/etc/profile中

编译，增加了调试信息：

g++ -o hi hi.cpp -I/usr/local/include/ -lhiredis -g

代码：

#include <stdio.h>

#include <hiredis/hiredis.h>

 

main()

{

  redisContext* conn;

  redisReply *reply;

 

  conn = redisConnect("127.0.0.1", 6379 );

  if(conn->err){

    printf("connection error: %s\n", conn->errstr);

    //return -1;

  }

 

  reply = (redisReply *)redisCommand(conn, "auth redispass");

  if( NULL == reply )

    return -1;

  printf("reply str is: %s\n", reply->str );

  freeReplyObject(reply);

 

  reply = (redisReply *)redisCommand(conn, "set city hangzhou");

  if( NULL == reply )

    return -1;

  printf("reply str is: %s\n", reply->str );

  freeReplyObject(reply);

 

  reply = (redisReply *)redisCommand(conn, "get city");

  if( NULL == reply )

    return -1;

  printf("reply str is: %s\n", reply->str );

  freeReplyObject(reply);

 

  redisFree(conn);

}
